APOD: IRAS 20324: Evaporating Protostar (2013 Sep 04) Image Credit: NASA, ESA, Hubble Heritage Team (STScI/AURA), and IPHAS http://apod.nasa.gov/apod/ap130904.html Explanation: Will this caterpillar-shaped interstellar cloud one day evolve into a butterfly-shaped nebula? No one is sure. What is sure is that IRAS 20324+4057, on the inside, is contracting to form a new star. On the outside, however, energetic winds are blowing and energetic light is eroding away much of the gas and dust that might have been used to form the star. Therefore, no one is sure what mass the resulting star will have, and, therefore, no one knows the fate of this star. Were the winds and light to whittle the protostar down near the mass of the Sun, the outer atmosphere of this new star may one day expand into a planetary nebula, possibly even one that looks like a butterfly. Alternatively, if the stellar cocoon retains enough mass, a massive star will form that will one day explode in a supernova. The eroding protostellar nebula IRAS 20324+4057 spans about one light year and lies about 4,500 light years away toward the constellation of the Swan (Cygnus). The above image of IRAS 20324+4057 was taken with the Hubble Space Telescope in 2006 but released last week. The battle between gravity and light will likely take over 100,000 years to play out, but clever observations and deductions may yet yield telling clues well before that. http://heritage.stsci.edu/2013/35/ http://hubblesite.org/news/2013/35 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130904 #APOD
